ABSTRACT
AIM: To evaluate the quality of Rhizoma gastrodiea processed by different drying methods. METHODS: Vacuum freeze drying and oven drying were adopted. The content of gastrodin was determined by RP-HPLC. RESULTS: The content of gastrodin of Rhizoma Gastrodiae processed by vacuum freeze drying was significantly higher than that by boil with water and oven drying. CONCLUSION: The method of vacuum freeze (drying) can prevent Rhizoma Gastrodiae from degradation of gastrodin, to keep the appearance, to make Rhizoma Gastrodiae convenient for further processing.
ABSTRACT
Human and horse polyvalent immune serum and immune globulin were used to control experimental pseudomonas aeruginosa sepsis in burned and unburned mice. The results indicated that the survival rates for the human immune preparations ranged from 70-85.7%; and that for the horse immunoglobulin ranged from 71.4-90% Furthermore, surviving mice showed a shortening of clinical course with rapid abatement of symptoms and signs. The,survival rate was 14.8-20% in untreated control groups, and most of the mice died in 1-4 days after, infection.It is therefore believed that this immunological approach is an efficacious adjunctive measure in controlling life-threatening infection caused by pseudo-monas aeruginosa.
ABSTRACT
The effect of postburn serum on T lymphocyte proliferation response was studied. The results showed that postburn serum was able to inhibit T lymphocyte transformation. The degree of serum suppression correlated with reduced T lymphocyte transformation after burn. Postburn serum also showed significant suppressive activities upon both interleukin 2 (IL-2) production and interaction betweeen IL-2 and IL-2 receptor (IL-2R), but had no significant effect on interleukin 1 (1L-1) producticn. This result indicated that postburn serum might inhibit IL-2 production and response through certain pathway other than IL-1 production, resulting in impaired T lymphocyte proliferation response.
